MODIFICATION CLASSIFICATION

MAJOR 55696S18546

MINOR None

NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the

mass, balance, structural strength, reliability, operational characteristics affecting the

airworthiness of the product. All other changes are major changes.

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

A new Flight Control Secondary Computer (FCSC) standard, named L20M19, was developed to take

into account the last FCSC software evolutions.

This Service Bulletin is published to advise all operators of A340 aircraft with mechanical rudder

(aircraft on which Mod. No. 49144S16279 (FLIGHT CONTROLS - ELECTRICAL FLIGHT CONTROL

SYSTEM (EFCS) - INSTALL RUDDER FLY-BY WIRE ON A330/A340) is not embodied) of the issue of

THALES AVIONICS Service Bulletin No. B492AAM-27-014.

This Service Bulletin recommends introduction of new software "L20M19" PN B492AAM0411 on the two

FCSCs by means of On-Board Replaceable Modules (OBRMs) replacement or reprogramming or

FCSCs replacement.

Accomplishment of this Service Bulletin introduces the following improvements :

- new elevator position monitoring,

- improvement of other computers monitoring,

- improvement of rate gyro units monitoring.

The "new elevator position monitoring" function, that will allow to cancel red Operation Engineering

Bulletin (OEB) No. 54, will be active at aircraft level only if FCSC standard L20M19 standard is

associated with future Flight Control Primary Computer (FCPC) standards. It is anticipated that an

Airworthiness Directive (AD) will mandate modification of both FCSC and FCPC.

This Service Bulletin is published to advise all operators of A340 aircraft with

Only in the case of these associations, the operational consequences of this Service

Bulletin are the modifications of the Flight Manual (FM).
